STENCIL-CUTTING MACHINE.

Specification of Letters Patent.

| I To all whom of may concern:

Be it known that I, ORLANDO S. WATTS, a citizen of the United States, residing at 766 Line St, Camden, in the county of Camden and State 01"" New Jersey, have invented new and useful improvements in Stencil-Cutting Machines, of which the following is a specification. I

The invention. relates to stcncil-cutting machines, and more particularly to machines which operate in the nature of a typewriter, to cut stencils which may later be used for form letters, notices, circulars and. the like.

The invention is particularly adapted to a typewriting machine, and to this endconsists more particularly in an attachment for a typewriting machine, whereby with the use of the attachment it will be possible to make the typewritin machine-more e'fiicient in thecutting of stencils.

Although I may particularly adapt my stencil-cutting" attachment to a Hammond typewriter, a type of machine that is Well known ,in the trade, it will be understood that I may adapt the attachment to various other forms of typewriting machinery and may, if desirable, construct a machine along the lines of my lnvention which will be particularly adapted to stencil cutting.

In the further disclosure of the invention, reference is to be had to the accompanying drawings,- constituting a. part of this specification, in which similar characters of reference denote corresponding parts in all the views, and in which- Figure 1 is a fragmentary elevation showing my device applied to a typewriting machine, parts being shown in section to disclose the underlymg structure.

Fig. 2 1s a fragmentary vertical sectional view taken on the line 2-2 in Fig. 1, and

' Fig. 3 is a fragmentary plan view taken on the line 33 n Fig. 1.

Referrin more particularly to the views,

the numeral 10 indicates what may be termed the traveling carriage frame of a typewritlng machme, that is to say, the frame which, as is Well known, travels back and forth 'with the carriage and roller of the typelarly employ my device With-a Hammond typewriting machine, one reason therefor being that the paper-holding drum of a Hammond typewriting machine is hollow and in which my attachment can be readily placed. For insta/nce, I provide a trough 11 which is adapted to contain a suitable fluid 12 used in connection with a stencil sheet 13, the fluid being generally known in the trade as dermax fluid, and the trough 11 is arranged in the usual paper-holding roller 1a of a Hammond typewriting machine. Within this trough there is arranged to turn a cylinder 15, journaled by means of suitable studs 16 to the carriage 10 of the machine, the studs carrying suitable operating knobs 17 on their ends, so that the cylinder 15 can be rotated Within the trough. The cylinder 15 is provided with a longitudinal slot 18 to permit of the reception of an apron 19 carrymg on its inner end a' rod 20 to which the apron is attached, the rod 20 being larger .than the slot 18 so that the inner end of the the stencil sheet is wound up on the cylinder,

it will be wound around the wound-up apron, and therefore commg in contact with the dcrmax fluid in the trough, both sides of the stencil sheet will be subjected to theaction of the fluid, and later when the stencil sheet is in an extended position, the apron will tend to keep the stencil sheet in a moist and proper condition for stenciling. Risin from; the frame 10 and attacl'ied thereto is a supplementary frame consisting of a. bracket 23 on each side, said bracket having" a slot 24; in. which operates a thumb screw 25 ittached to the lower end of a rod 26, tb upper end of which is attached to a hearing 27 or shaft 2.8. v Wit-h rthis construction it will be seen that the shaft can be lowered or raised relative-tothe carriageyhy means heretofore, endit will be seen some time.

of the thumb screw 25 sliding entire-piste or bracket 23, and that one of the supplementary frames 22 is errengedon each side of the carriage frame to support the shaft 28 in nhorizorital position. Spools 2? are keyed to the shaft 28 end cords or elaetlcs 30;

are wound around the spools with their-free ends secured thereto, the other ends of the cordsor elostics being e opted for snitch e connection with the upper end of the stencil sheet 13, by providing bayonet slots 31 m the stencil sheet in which buttons 32 on the ends of the'cords or elastics are attached, said bayonet slots receiving shown. ln this manner the stencil sheet can he held in tension; us will elsobe clearly seen by referring to thqviews. n

\ A pawl; und ratchet mechanism 33 is urronged upon the heft 28 by having the ratchet, indicu'tcd by the numeral 34, keyed to the shaft and the pawl 35 mounted on the supplementary frame, thus preventing reverse movement of the shaft 28. The shaft 28 also carries a pulley 36, and at similar pulley 37 is secured on one of the studs 12 with or chain or belt 38 connecting the pol leys 36 and 37, so that the rotation of the cylinder 15 will bring about rotation of the shaft 28, thus exerting a, pull on the stencil sheet to hold the some in machine is'opereted to rotate 15. Or the cylinder 15 may to the usual type roller and actuated thereby, as will beohviousu With the 'form of construction described, it will be clear that when lSdGVllCB is used in connection with e typewriting machine, as mentioned heretofore, the typewriter keys are operated in the usual manner tocut the stencil and do the necessary stenciling,

the cylinder the sheet being kept in proper condition by the dcrnnrx fluid in the trough, as mentioned 'cnrriesjs tremereaches the end of its movenwnl. and is returned to lllltllll position, the relation of. the paper roll will bring about of the supplementary frame, whereby the stencil sheet will be advanced upwardly one ortwo spaces, as the case may be, and at the unroll a corresponding the stencil sheet from the cylinder 15. tension of the stencil runyegncnl. together cords or elmitics 30011 the spools 2 reirn'rh pruciically the same.

A structure of this cherecter used in con ncclion with u typewriting machine as on attachment thereof, enables stenciling to he m-complishcd in u very economical manner, and by having the trough ill with the tier" mux fluid therein, the arrangement of the stencil sheet by connection uith'the apron The sheet will, by this up: with the winding up the buttons, as.

tension when the he genred direct connecting the stenci that [when the.

length of mg saidslicet'relative to the carriage and the sliding of the a indcr, can be accomplis red without soiling, the hands with the dermax flui the stencil sheet can be n'ioiste ned any number of times without r ntrlpving the some from the machine, by simply reversing the; movement oi the stencil sheet in the machine. Another adthat-111s simple arrangevantage Wlll be, mentof the device and the confinement of ythedermax uid, willprevent gummingg of the methenism of the'typewriting machine, and. the "demise 'fluid vwill be supplied mm the rcse voir to the stencil as needed, thus preventing the stencil from getting dry along the working part. of a visible typewritinlg machine, the stencil will also be open to i spection at all times and will be visible to the operator, and confining the dermai: fluid in the fluid can he used over (again after a stencil has heenoompleted. y

it Will of course be understood that I may use any preferable form ,or kind of stencil sheet to accomplish the desired result, and that although 1 have shownv a particulariorm of my machine, various slight changes may he made without departing from the s irit of the invention, the scope of which ischine and the traveling carriage rame thereof, at fiuid-contammg trough movable with the carriage frame, it rotatable cylinder in said trough, an apron connected to said 'cylinder and adopted to be wound or un wound thereon, a, ster *il sheet, means for 'l sheet to the apron, a supplementary frame, means on the su plem enmry frame and connecting with t e stencil sheet to hold the some in tension, means for adjusting the sup frame relative to the carriage creme, on
